Abstract: PURPOSE:To surely extract the logical level of a received signal even when a transmitting signal and a receiving signal are simultaneously transmitted onto one line. CONSTITUTION:A voltage D of a transmission line 13 is turned to a Vcc when both a transmitting signal A and a receiving signal C are at a logical level '1', turned to Vcc/2 when any one of the signals A and C is at the logical level '1', and turned to 0V when the both signals A and C are at a logical level '0'. When the transmitting signal A is at the logical level '1', a transistor Tr is turned off and when the signal A is at the logical level '0', the Tr is turned on. Therefore, a threshold voltage B is turned to 3/4Vcc when the transistor Tr is turned off, and turned to Vcc/4 when the transistor Tr is turned on. Thus, the logical level of a voltage E outputted by a comparator 12a applying the voltage D to the (-) terminal and applying the above-mentioned threshold voltage B to the (+) terminal is turned to the received signal E at the same logical level as the receiving signal C.

Title: Method for managing hash entry area
Inventor: KITO MASAMI
IPC: G06F17/30
Filed: 1990-03-30
Abstract: PURPOSE:To make it possible to add a data area without changing hash logic by forming a primary entry area having plural blocks and a secondary entry area having the same number of blocks as that of the primary entry area. CONSTITUTION:The size of a has entry range is determined as entry block numbers 0 to 3 e.g. and the size of the secondary entry B is set up to the same entry block numbers 0 to 3. In the case of extending the secondary entry, the same numbers 0 to 3 are allocated. When the block number 2 of an accessed destination is transmitted to a file accessing part 3, the accessing part 3 reads out the leading address of the primary entry range A, accesses the block 2 of the data area 1 based upon the read address and checks the existence of the entry of an objective account number. When the entry concerned does not exist, the existence of the data area 2 to be the secondary entry B is detected and the block 2 is accessed. When he objective entry is obtained, a prescribed access is applied to the objective entry.

Abstract: PURPOSE:To make it possible to perform the clear detection of a target by avoiding the jamming of an arrival interference wave, by emitting the radar transmission signal of the polarized wave crossing that of the arrival interference wave at right angles from a radar antenna. CONSTITUTION:The characteristic analysis of a polarized wave is performed by such a method that the amplitude and phase of a horizontal component H are compared with a vertical component V as reference by a signal processing means. According to this result, an arrival interference wave is changed over to horizontal, levorotatory and dextro-rotary polarized waves corresponding to respective vertical, horizontal, dextro-rotary and levorotatory polarized waves by a polarized wave synthesizing circuit 7 and the transmission signal of the polarized signal crossing that of the interference wave at right angles is emitted from an antenna 1. Because the radar transmission signal strong in autocorrelation having a signal mode unaffected by jamming of the interference wave is reflected from a target to be guided to a receiver 4 as mentioned above, the jamming of the arrival interference wave is avoided by a signal processor 5 and the detection of the target can be performed.

IPC: A61P31/04
Filed: 1989-04-05
Abstract: Lymphocytosis promoting factor (LPF) and filamentous hemaglutinin (FHA) are isolated from the growth medium of the Bordatella pertussis organism and purified by selectively adsorbing the LPF and FHA on a selective adsorbing medium, such as filter aids or gel filtration media, at low ionic strength and subsequently removing the adsorbed LPF and FHA using an aqueous medium of high ionic strength, either simultaneously or sequentially. Prior to desorption of the LPF and FHA, the adsorbing medium may be contacted with an aqueous solution of an non-ionic detergent, which enables the LPF and FHA subsequently desorbed to be substantially free from contamination by lipopolysaccharides (LPS). The LPF and FHA may be further purified on hydroxyapatite. The LPF and FHA may be detoxified separately or together by contacting with a cross-linking agent, such as glutaraldehyde or formaldehyde, in the presence of an anti-aggregation agent. The resulting purified and detoxified LPF and FHA may be used to formulate a vaccine against pertussis.
